1. Technical description.
1.1. General description.
Stabilized DC power supply is intended for supply equipments that require stabilised voltage of
12V DC.
When connected to
fuse blocks of the LB4/xx/xx or LB8/xx/xx family, the power supply unit can feed more equipments (max. 4 or 8). The power supply
unit is protected against short-circuit, overload and overvoltage.
